When nothing appeals, the goal shifts from eating well to eating something, and the easiest wins are cold, plain, and liquid. Prioritise protein and fluid, accept that variety has gone for now, and treat a run of days where you eat almost nothing as a reason to call your prescriber rather than something to manage alone.
Not eating is not the goal, even though it may feel efficient. Appetite suppression is doing the restricting for you, and intake can fall far below what your body needs without hunger ever signalling it.
Signs it has gone too far: feeling cold all the time, hair shedding, persistent exhaustion, dizziness on standing, periods becoming irregular. Those together mean intake is too low. If you notice relief at having a reason not to eat, that is worth saying out loud to your prescriber, and the National Alliance for Eating Disorders helpline is available for support.
For how this fits alongside the rest of eating and training on a GLP-1, see Eating and Training on a GLP-1: The Complete Guide.
Why nothing appeals
Several things at once. Appetite signalling is suppressed. Food sits longer, so the idea of adding more to a full stomach is unattractive. Smell aversion often runs ahead of taste, which is why cooking becomes harder than eating. And once a food has made you feel sick, aversion to it can persist long after.
Knowing it is mechanism rather than willpower makes it easier to work around instead of arguing with.
Cold beats hot
The single most useful adjustment. Hot food releases aroma; cold food barely does. If smells are what turns you off, the same meal straight from the fridge is often manageable.
Yoghurt, cottage cheese, cold chicken, tinned fish, hummus, hard-boiled eggs, cold noodles, overnight oats. None require cooking, which removes the other obstacle.
Liquid when solid is impossible
Drinking calories is easier than eating them when your stomach is slow and your nose is objecting.
Protein shakes, milk, kefir, smoothies, and soups or broths all count. On the worst days a shake is often the difference between adequate protein and none, and that is a genuinely good outcome rather than a compromise.
Sip rather than gulp, since volume at once is what causes trouble.
Plain and dry for queasy days
Crackers, toast, plain rice, oats, plain potato. Unglamorous and frequently the only things that work.
These are low in protein, so pair them with something when you can rather than making them the whole day.
Small and frequent
Three meals is the wrong target when each one defeats you. Several small amounts through the day adds up to more than two abandoned plates.
Setting a loose reminder helps, because without hunger there is nothing prompting you to eat at all. Many people simply forget.
Work with your week
If the days after your injection are worst, put the cold and liquid options there and anything more appealing later in the week.
Do not shop or plan on a bad day. Everything looks repellent and you will come home with nothing.
When to call
Several days of eating almost nothing. Not keeping fluids down. Losing weight much faster than expected. Dizziness, persistent exhaustion, or feeling cold constantly.
There are options: slowing the titration, stepping back a dose, treating specific symptoms. Your prescriber has more room than most people assume, and none of it happens if they do not know.
Cold food releases far less aroma, which is why the no-cook protein options matter more than recipes here. If this has run for days rather than hours, the signs intake has gone too low is the page to read next.
Frequently asked questions
Is it fine to eat very little if I am not hungry?
No. Your body needs protein and nutrients regardless of appetite, and low intake causes muscle loss, fatigue and deficiencies.
Can I just have shakes?
As a bridge through a bad patch, yes. As a long-term approach it is worth discussing with a dietitian.
Why does everything smell awful?
Smell aversion is commonly reported. Cold food is the practical workaround.
Will appetite return?
Many people find it settles at a given dose and dips again after each increase.
What if I have no appetite at all for weeks?
Tell your prescriber. That is a reason to adjust something rather than to continue as you are.
Should I force myself to eat?
Not to the point of misery. Eat something adequate rather than nothing, and get help if adequate is out of reach.
